Arena changes

• W: Base damage changed to 30 to 130.
• E: Cooldown changed to 20 to 14 seconds.

• Jax builds Trinity Force as a first or second item in most games.³
• Mystic Punch with Reverberation is a strong combination for Jax.⁴

• Shareholder does not work with augments that grant an item, but Spatula can still work: a Jax who completed Spatula received Shardblade afterward.⁵

Earlier formats

• Jax can make full use of the attack damage and ability power from Master of Duality.⁷ 8x2 duos
• Weighted augments work well on Jax.⁸ 8x2 duos
• Mystic Punch is useful for Jax because he attacks quickly, has high cooldowns, and does not need critical strike chance.⁹ 8x2 duos
• Against ranged champions such as Quinn, Vayne, and Kennen, Phase Rush can help Jax use Q and basic attacks to trigger it, then use E to stun and disengage.¹⁰ 8x2 duos
• When Jax activates his ultimate, his passive on-hit damage applies every two attacks instead of every three for the ultimate's duration.¹¹¹² 8x2 duos
• Back to Basics locks Jax out of both parts of his ultimate: its on-hit damage and resistances.¹³ 8x2 duos
• Back to Basics does not disable Jax's ultimate passive.¹⁴ 8x2 duos
• Dusk and Dawn pairs well with Jax because it works well with auto-attack resets, three-hit passives, and on-hit effects.¹⁵ 8x2 duos
• Marksmage damage does not apply on auto-attack-enhancing abilities such as Jax's W.¹⁶ 8x2 duos
• Jax is strong with items already, so there is no need to force anvil builds.¹⁷ 8x2 duos
• Hybrid champions such as Jax can benefit from Might shards, and anvil builds can work well for them.¹⁸ 8x2 duos
• Jax's on-hit effects stopped working during a round; Mystic Punch stopped reducing E's cooldown, and Chain Lightning did not trigger. Chain Lightning might not have triggered because Yunara was not near Sion, and the damage item tooltips might have been bugged.¹⁹ 8x2 duos
